A brand-new 1993 Porsche 911 Carrera RSR 3.8 will be auctioned on Saturday, May 27, at VILLA ERBA, Italy by RM Sotheby’s.

This “unused” RSR 3.8 is one of just 51 examples produced and has only 10 kilometres recorded on its odometer, which means it vanished into a private collection right after it was delivered, and remained untouched and undriven for nearly 25 years. Thus, it’s still covered with with its factory-applied Cosmoline coating.

Specs-wise, this Turbo-bodied racing version of the Carrera RS was equipped with a 3.8-litre type M64/04 RSR-specific engine. This dry-sumped, single-ignition power unit was able to deliver an impressive 350 horsepower and 284 ft-lb of torque, all fed through an uprated five-speed manual transaxle. However, unbiased reviewers viewed those official numbers as very conservative. A more realistic figure, they declared, was at least 375 horsepower. According to a test drive conducted by “Car and Driver” magazine, the RSR 3.8 produced a 0–60 mph result of 3.7 seconds, which is faster than the Ferrari F40.

Furthermore, the RSR 3.8 also achieved stunning race results in the past, winning overall at the Spa 24 Hours, Suzuka 1000 KM, 24 Hours of Interlagos, and many others.

This 1993 Porsche 911 Carrera RSR 3.8 is expected to fetch up to €2,200,000.
